813 * the application is inactive (i.e. no events fire) and we don't want to
814 * wait for another modifier state change to detect such a change.
816 * NSEventModifierFlagCapsLock requires a special treatment. The other flags
817 * are handled in similar manners.
819 * NSEventModifierFlagCapsLock
820 * ---------------------------
822 * If CapsLock state is changed, "up" and "down" events will be fired in
823 * sequence, effectively updates CapsLock state on the guest.
828 * If a flag is not set, fire "up" events for all keys which correspond to
829 * the flag. Note that "down" events are not fired here because the flags
830 * checked here do not tell what exact keys are down.
832 * If one of the keys corresponding to a flag is down, we rely on
833 * -[NSEvent keyCode] of an event whose -[NSEvent type] is
834 * NSEventTypeFlagsChanged to know the exact key which is down, which has
835 * the following two downsides:
836 * - It does not work when the application is inactive as described above.
837 * - It malfactions *after* the modifier state is changed while the
838 * application is inactive. It is because -[NSEvent keyCode] does not tell
839 * if the key is up or down, and requires to infer the current state from
840 * the previous state. It is still possible to fix such a malfanction by
841 * completely leaving your hands from the keyboard, which hopefully makes
842 * this implementation usable enough.
